Technical Field

[0001] The utility model relates to the field of aluminum alloy lined plastic pipes, in particular to a novel aluminum alloy lined plastic pipe. Background Art

[0002] Aluminum alloy lined plastic composite pipe is a new type of practical pipe developed on the basis of traditional plastic pipes. It combines the physical and chemical advantages of metal and plastic materials. It has the advantages of light weight, 100% oxygen resistance, UV resistance, clean and hygienic installation, strong sealing and maintenance-free in water supply pipe applications. It solves the defects of plastic pipes such as bending after thermal expansion and contraction, fear of impact, and easy aging in indoor open installation.

[0003] In the prior art, the outer layer of the aluminum alloy lined plastic composite pipe is generally an aluminum alloy pipe, and the inner layer is a thermoplastic plastic pipe. When the water pressure flowing in the pipe is too high, it will impact the inner wall of the inner thermoplastic plastic pipe and cause the pipe to rupture. In addition, the internal liquid circulation impacts the inner wall of the pipe and generates a lot of noise that affects the physical and mental health of people around.

[0004] Therefore, the utility model provides a novel aluminum alloy lined plastic pipe to solve the problems raised in the above background technology. Utility Model Content

[0008] Through the above technical solution, when the pipeline is transporting liquid, the liquid impacts the fan blades, driving the fan blades to rotate on the bearing seat to disperse the subsequent liquid impact force, reduce the impact force of the liquid on the pipeline, and reduce the noise caused by the liquid circulation pipeline to a certain extent.

[0009] Furthermore, the aluminum alloy tube comprises a metal layer and a heat insulation layer, the heat insulation layer is sleeved and arranged outside the heat insulation layer, the metal layer material is a seamless aluminum tube formed by hot extrusion, and the heat insulation layer material is a thermoplastic plastic tube;

[0010] Through the above technical solution, when transporting liquid with high temperature, the insulation layer isolates the liquid temperature in the pipeline to avoid the loss of liquid temperature during transportation. The metal layer can effectively resist ultraviolet rays in the sun and resist aging to enhance the service life of the pipeline.

[0011] Furthermore, a fixing sleeve is fixedly provided on a side of the second clamping block away from the flange, a pull rod is sleeved in the fixing sleeve, and a spring is sleeved in the fixing sleeve;

[0012] Through the above technical solution, the shaking of the pull rod during movement is reduced, the collision between the pull rod and the spring is reduced, and the use efficiency is improved.

[0013] Furthermore, one end of the pull rod passes through one side of the second clamping block and is inserted into the limiting groove, and the spring is fixedly arranged outside the pull rod;

[0014] Through the above technical solution, the pull rod is pulled to adjust the position of the pull rod for movement, exposing the limit groove on the No. 2 clamping block, and the No. 1 flange is rotated through the rotating shaft to make the No. 1 flange and the No. 2 flange perpendicular to each other up and down, and the pull rod is pulled to adjust the position of the pull rod for movement.

[0015] Furthermore, the limit block is embedded in the limit groove, and one end of the pull rod is embedded in the slot;

[0017] Furthermore, the second hole on the first flange and the second hole on the second flange are vertically aligned in pairs, and the two opposite fixing blocks on the aluminum alloy tube are respectively embedded in the second holes of the first flange and the second flange that are opposite to each other;

[0018] Through the above technical solution, the two aluminum alloy tubes are fixed in position by embedding the opposite fixing blocks on the two aluminum alloy tubes into the opposite No. 2 holes of the No. 1 flange and the No. 2 flange, respectively, thereby enhancing the sealing performance of the connection between the two aluminum alloy tubes.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes a new type of aluminum alloy lined plastic pipe, in which a No. 1 connecting rod is placed in a No. 1 hole where a No. 1 flange and a No. 2 flange are opposite to each other. When conveying liquid, the liquid flows inside the flange to drive the fan blades to rotate on the bearing seat through the No. 2 connecting rod. The thrust generated by the rotation of the fan blades offsets the impact force of the subsequent liquid circulation, thereby reducing the impact force of the pipeline when the liquid flows, and reducing the noise caused by the impact of the liquid circulation pipeline on the pipeline to a certain extent.
